Even something as small as an eyeball, has multiple parts within it. The retina at the back of the eyeball is responsible for the clarity of vision. The central area of the retina is known as the macula. Macular degeneration is the deterioration of this part of the retina. Macular degeneration is age related and is considered as an incurable condition. People suffering from macular degeneration experience blurred vision, black spots and may eventually lose central vision while retaining peripheral vision.
There are two types of macular degeneration; wet and dry. The dry form of this disease is more common than its wet form. Of these, the latter causes more serious vision loss. Dry macular degeneration leads to white or yellow deposits on the retina leading to further degeneration. In the wet form of this disease, blood vessels beneath the retina start growing towards the macula and may pull it away from the base when they break or leak fluid.
There are three stages of age related macular degeneration (AMD):
Macular degeneration is considered to be incurable, but certain forms of treatment can improve vision and slow down the rate of deterioration. Treatment prescribed by a doctor depends on stage of the disease and whether it is wet or dry. Studies suggest that a diet rich in Omega-3 fatty acids can prevent AMD and lower the risk of its progression.
